Electrical safety testers are instruments used to test diverse electrical safety such as testing outlet polarity, line voltage level, ampere rating, medical equipment, and others. These instruments can be used for many different types of measurements including AC or DC dielectric strength, insulation resistance, grounding systems resistance, earth continuity, AC or DC hipot, outlet polarity, line leakage, and appliance testing. Electrical safety testers may also be used for other measurement...

Design TrendsTop

Q:
What new technologies are influencing electrical safety tester design?
7 answers
Answers:
Safety Testers must be designed so that a test technician cannot cheat on any tests - a good test report can only show "good," if all tests had good results. The test objects must clearly be defined, for example, be read by the tester with bar codes that are stored with the test results.

FeaturesTop

Q:
What would your design or feature "wish list" be for this product?
